Marvin Ross’s groundbreaking catalogue of jewelry in the Byzantine Collection at Dumbarton Oaks was first published in 1965. The volume has long been out of print, but its enormous popularity and enduring status led to a reprint, this time with color photographs. Accompanying the reprint edition is an addendum by Susan Boyd and Stephen Zwirn with twenty-two new objects acquired by Dumbarton Oaks Collection between 1962 and 1999.
